The members of this class provide nodes for comparisons to make a decision. The result of a comparison is "True" or "False" or, in a bit-wise notation, 0 and 1; it determines which route the graph will follow. When you create a condition you compare two values against each other with an operator. Operators are, for example, "equal to'", "greater than", or "less than or equal to". Conditions cannot only be used with single elements, but also data types which support more than one value – – these types are called arrays. A typical array are the position of the data of an emitter's particles. The "FilterBy" nodes have been designed for exactly this purpose. When the condition is fulfilled, the array will only contain the elements that satisfy the given condition. The other, "false", elements are removed.
